INTRODUCTION Stryker VAV Controller is a pre-programmed configurable controller. It can be configured using ‘VAV Configuration Wizard’. This configuration wizard is developed under WEBStation-AXTM software tool.
Stryker™ BACnet VAV Controller The Honeywell Stryker controller is a configurable controller. It supports two applications,
1. Without actuator 2. With actuator
User can select any one of the applications and configure the controller accordingly. Each application has various configurable settings, which provide multiple options and flexibility to user. For such settings, network variables are provided in the BACnet VAV controller. Configuration of the BACnet VAV controller involves selection of the appropriate settings from available options as per the requirement. These controllers are configurable using the NiagaraAX Framework® software.
WEBStation-AXTM
The WEBStation-AX™, powered by the Niagara AX Framework® is a flexible network server for all connected WEBs-AX controllers. WEBStation-AX™ creates a powerful network environment with comprehensive database management, alarm management and messaging services. WEBStation-AX™ hosts an application called ‘BACnet VAV Configuration Wizard’, which provides an engineering environment for configuration of BACnet VAV controller.
Features
• Provisioning of the multi-controller systems (tools for updating and installation of software modules).
• Central database storage for attached controllers. • Archive destination/repository for log and alarm
data. • Central server of graphics and aggregated data
(single point of access to the system – one IP address).
• Platform for optional enterprise applications. WEBStation-AX™ acts as a network server or a ‘Supervisor’ for all connected WEBs-AX™ Controllers. It creates a network environment for the management of these controllers, alarms and messaging services.
BACnet VAV Configuration Wizard It is a special application developed in the WEBStation-AX to configure the BACnet VAV controller. All configurable network variables of the VAV controller are accessible through this application for configuration. BACnet VAV Configuration Wizard provides a mean to select settings for all components of the BACnet VAV system, control strategy and parameters as per the application requirement. Following operations can be performed using WEBStation-AX and Configuration Wizard: 1. Add a Stryker VAV controller on the BACnet network. 2. Configure and set the parameters as per the
application requirements. 3. Create a database by discovering the objects and
adding them on Niagara level, which can be used for global programming if required. These points can also be bound to graphics if graphics is generated for the application.
4. Download and upload the configuration into the selected BACnet VAV. (Online Operation). Monitoring the points and operation of the BACnet VAV. (Online)
5. Set the time and date (Online Operation) 6. Calibration of sensors (Online Operation) 7. Manual Mode/Diagnostics: In this operation, device
can be put in manual mode to override the outputs. Mainly it is useful during commissioning for point to point testing.(Online Operation)
8. Alarms: Alarms can be monitored using ‘Alarms’ menu (Online Operation)

Control Application
VAV systems in commercial buildings typically incorporate a central air handler that delivers a modulated volume of air at a preconditioned temperature to multiple zones. Each zone is served by a VAV terminal box unit. Each box incorporates an airflow pickup assembly and motorized damper with optional fan and/or reheat coil. The controller determines and regulates the airflow of conditioned air to the space.
The zone being served by the terminal box will use a TR2X Wall Module or a Zio (TR71/TR75 only) Digital Wall Module for space temperature determination and access to the BACnet MS/TP network for operators. Figure 1A shows a typical VAV box control application for the CVL4024NS-VAV1/U controller. Figure 1B shows a typical VAV box control application for the CVB4022AS-VAV1/U controller.

Control Provided The Stryker BACnet VAV Controllers are primarily intended for pressure independent, single duct VAV box control. Pressure independent control specifies that the individual zone terminal unit have a means for maintaining a consistent volume of air into the zone regardless of the input static pressure. The controller modulates the airflow into the zone to satisfy the Zone Temperature Setpoint. Minimum Airflows are maintained except during emergency strategy periods or during building Unoccupied periods if using physical position stops, a minimum / maximum airflow is always maintained. Pressure dependent control specifies that the damper position is controlled by space temperature only and not by a measurement of airflow volume. The amount of air delivered to the zone at any given damper position is dependent on the static pressure in the supply air duct (physical position stops, range stop pins, are used to keep the damper at a fixed position). Additional outputs are available for control of heating systems such as reheat coils for Heat mode or Morning warmup mode operation. The heating equipment can be staged resistive heating, staged 2-position (solenoid) valve, or modulated steam or hot water valve.
VAV Configuration Requirement VAV controller can be configured using two methods:
1. With WEBStation-AX Software Tool 2. Through TR75 Module
With WEBStation-AX Software Tool In the WEBStation-AXTM software tool, VAV Configuration Wizard application is integrated for VAV controller configuration. 1. Configuration through PC
VAV controller can be accessed with the personnel computer with WEBStation-AXTM software tool installed on it. A VAV controller can be accessed for configuring, uploading and downloading operations through BACnet adaptor, which connects a PC through an Ethernet cable.
2. Configuration through WEBs Controller
If the VAV controller is connected to the BACnet network of WEBs controller, it can be accessed through WEBs controller using PC with WEBStation-AXTM tool installed on it. When WEBs controller is already commissioned, then it can be accessed through IP address with personnel computer without WEBStation-AX
software tool installed on it. All required operations on the Stryker VAV controller can be performed by accessing WEBs controller through Web browser.
Through TR75 Module Configurable network parameters are also accessible through TR75 wall module. From the wall module, VAV application can be configured as per requirement. Access to the configurable parameters is password protected with default password 0000. For details, refer to ‘Stryker VAV Zio Configuration Guide.’

IMPORTANT All the Honeywell WEBs software tools are now signed. Users can verify the signature using any OpenSSL tool. Below are the steps to verify signature using OpenSSL community distribution. Prerequisites:
• Download the Honeywell public key BuildingsCommonSupervisor.crt from location- same location as the software release location
• Download the batch file “VerifyWEBsToolsSignature.bat” from location- same location as the software release location. This file has the commands to verify the module signature using the public key specified in Step 1
• Download OPENSSL from this link- https://www.openssl.org/source/openssl-1.0.2o.tar.gz • Extract the file using any ZIP utility to get the folder “openssl-1.0.2o” • In the extracted folder find the file “openssl.cnf” • Set Windows environment variable OPENSSL_CONF=<PATH TO openssl.cnf>, for example
OPENSSL_CONF=C:\openssl-1.0.2o\apps\openssl.cnf Steps to verify the signature:
1. Place the files BuildingsCommonSupervisor.crt, VerifyWEBsToolsSignature.bat, WEBs tools modules and signature file in the same location. For example: Following files are in one place
a. BuildingsCommonSupervisor.crt b. VerifyWEBsToolsSignature.bat c. honeywellSpyderTool.jar d. honeywellSpyderTool.jar.sig
2. Open the command prompt and navigate to the location of the above files. 3. Execute the batch file VerifyWEBsToolsSignature.bat against a module for verifying its signature, for example -
C:\Spyder_RELEASE\ > VerifyWEBsToolsSignature.bat honeywellSpyderTool.jar 4. OpenSSL will verify this module’s signature and printout the below verification details:
5. If the Niagara module is compromised then user will get the below log, where verification has failed:

Control Parameters In the control parameter screen of the Accessory Loops, parameters related to .PID loop and Auxiliary Output is provided.
Figure 106: Inputs for Reset Sensor
Control Parameters Following are the parameters of the PID loop: Main Control
Figure 107: Main Control Parameters
Throttling Range
It is the proportional change in the sensed variable. This variable is required to change the control output from 0 % to 100 %. The unit of the throttling range depends upon the unit of process variable. Integral Time (Default = 1650 seconds)
It is used to calculate the integral gain of the PID loop. The time in seconds is inversely proportional to the integral change per second. A setting of 0 eliminates the integral function. It ranges from 0 sec to 5000 sec
Derivative Time (0 seconds)
It is used to calculate the derivative gain in a PID loop. The time in seconds is directly proportional to the derivative effect per second. It ranges from 0 sec to 6553 sec. Derivative Time: Determines the derivative gain in a PID loop. The greater the time in seconds, the greater the derivative effect per second. PID Action: Direct Acting or Reverse Acting selection determines the behavior of the loop output.
Figure 108: PID Action
Direct: Set the PID action as ‘Direct’ if the loop output increase as the process variable increases. For example, space temperature is maintained by cooling valve. As space temperature increases, cooling valve is need to be modulated open to maintain the space temperature to the setpoint. In this case, PID action is ‘Direct
STRYKER BACNET VAV CONTROLLER
31-00103—02 84
Reverse: Set the PID action as ‘Reverse’ if the loop output decreases as the process variable increases. For example, space temperature is maintained by heating valve. As space temperature decreases, heating valve is need to be modulated open to maintain the space temperature to the setpoint. In this case, PID action is ‘Reverse.
Auxiliary Output Auxiliary digital output turns on when,
1. When the Occupancy Sensor is in Occupied or Standby Mode and Aux Do Action is selected as ‘Continuous.
OR 2. When PID output value exceeds the
‘Modulating Output Threshold For Aux’ value and ‘Modulating Control For Aux’ setting is ‘Yes’.
3. Accessory loop is enabled and first stage of the accessory loop is turned ON.
These settings are applicable if is configured in the Outputs screen of the Accessory Loops.
Figure 109: Auxiliary Output
Aux DO Action This determines the Aux DO behavior. The Aux output can be configured for either continuous or intermittent operation. • Continuous: If this option is selected, then auxiliary
output is always on during Occupied Mode and Standby Mode. During Unoccupied Mode and Bypass Mode, auxiliary output is turned ON intermittently.
• Intermittent: For all Occupancy Modes (Occupied,
Unoccupied, Bypass and Standby), the auxiliary output is turned ON intermittently
• Modulating Control For Aux If this option is selected as ‘Yes’, it allows the Aux DO to be controlled based on the value of the loops modulating output. It enables the ‘Modulating output Threshold for Aux’ field editable.
Modulating Output Threshold For Aux The accessory loop’s output is compared with this setpoint. If the output exceeds this setpoint value, auxiliary digital output turned ON.
Aux output minimum off time If auxiliary digital output is commanded OFF, it remains ON for this duration and then turns OFF.
Note:
When staged outputs are configured, this value must be configured to be less than (Cycler and stager interstage minimum on time - Aux output run on time).
Aux Output Run On Time It is a minimum time for which an auxiliary DO continues to run in ON state A value of 0 disables the run-on time. This is typically used when the AuxDo is configured for intermittent operation.
